Agents
Agents trade through onchain rule checks. Submitted trades that complete emit a trade or rule check refusal receipt with a hash of the submitted decision bytes. The hash verifies the bytes, not that a model produced them.

The protection market for AI traders.
Underwriters put USDG behind AI trading agents and set the premium. You pick a loss limit. If the market gaps through it, the agent stops and the bond pays the loss beyond it, up to a 30% drop. Anyone can call settle; there's no claim form. Robinhood Chain testnet, Paxos USDG.
Testnet. A capped, fully backed protection bond, not regulated insurance.

The difference
The agent bonds we've seen pay when an agent breaks a rule. Ours can't place a trade that breaks its rules; Bondline pays when the market breaks through your limit.
Why it's different
What sets it apart
- 01
A market, not a self bond: independent underwriters choose agents, set prices and earn premiums.
- 02
It pays market losses, not only agent failures or rule breaches.
- 03
Every cover is fully backed: the contract refuses a deposit unless the free bond already covers its worst case, and payouts are capped at a 30% drop.
- 04
It's real: Paxos USDG, Robinhood's official testnet Stock Tokens, Chainlink prices, and an onchain receipt for every completed trade and rule refusal.
One currency
Every dollar in Bondline is Paxos USDG: bonds, premiums, cover and claims.

In the news
AI agents already trade for people. The risk lands on the people.

Robinhood · the disclosure
“You assume all risk for trades executed by AI agents and for any use of your data by third-party LLM providers. Robinhood does not control, supervise, monitor, recommend, or audit agents.”
Bondline is where that risk gets priced and taken.
Three sides, one market
Who it's for
Underwriters
Underwriters put USDG behind an agent they choose, set the premium, and earn it. The contract caps what they can lose: it refuses a deposit unless the free bond already covers that deposit's worst case. An underwriter cannot release reserved bond or veto a payout by delisting. Settlement still depends on fresh prices and a successful USDG transfer, and unsolicited listed stock dust can currently block it.
Back an agentUsers
Users pick an agent and a loss limit, and pay the premium for cover. Past the limit, anyone can call settle. It stops the agent and pays once only if the required prices are fresh and the USDG transfer succeeds. The bond pays the loss beyond the limit, up to a 30% drop.
Get coverBuilt for agents
Any AI agent can use Bondline through our MCP server or SDK: list offers, quote cover and build unsigned transactions that its own wallet signs.

Every bond, cover and claim is a transaction on Robinhood Chain testnet. Submitted trades that complete emit a trade or rule check refusal receipt; offchain holds and decisions never submitted are absent.
